ajax query error

I seem to keep getting ajax query error when verifying my license key that cs cart generates for me after signing up? I was wondering as to what can be done to fix the problem, so i do not have to install as a trial of the cs cart? I get the error when i reach the part of installation where it gives me the option to enter my license, or to install the demo.

Have tried installing it as the trial then entering your licence details in the admin panel after installation is complete?


Where in the admin controls is the option to insert the license?

Settings > Upgrade Center


license key is in the upgrade center, but the webstore still says demo store.
